The World Wide Web (WWW), also called the Web, is an information space where documents and other web resources are identified by Uniform Resource Locators (URLs), interlinked by hypertext links, and accessible via the Internet. English scientist Tim Berners-Lee invented the World Wide Web in 1989.

The cut command removes the selected data from its original position, while the copy command creates a duplicate, in both cases the selected data is kept in temporary storage. The data from the clipboard is later inserted wherever a paste command is issued. Cut, Copy and Paste option are found in the edit menu.

Correct Answer: Option D (Only A and B)

Option A: Move a cursor across the screen
The Tab key does not move the cursor freely across the entire screen like a mouse would. Instead, it moves the cursor to the next tab stop. In exam terminology, this is considered “moving the cursor across the screen” because it shifts the cursor horizontally in fixed steps. Therefore, this option is treated as correct.

Option B: Indent a paragraph
This is one of the most common uses of the Tab key. When pressed in a word processor, it indents the beginning of a paragraph by moving the cursor to the right. This helps in keeping the document neat and well-formatted.

Option C: Move the cursor down the screen
This is incorrect. The Tab key does not move the cursor vertically. To move down the screen, you would use the Enter key or the arrow keys.

Option D: Only A and B
Since both Option A (in the intended sense of moving to tab stops) and Option B (indentation) are correct, the best answer is Option D.

Option E: None of these
This is wrong because both A and B are valid uses of the Tab key.

Therefore, the correct answer is Option D: Only A and B.
